5 3.Problems of TRIZ at OLYMPUS The reason why can not get an unexpected idea.
What is the problem of contradiction problem solving TRIZ?
Defining the contradiction problem from the root cause analysis into the existing system
How widen the field of view of the engineer for get the interesting idea ?
By thinking at solution around the root cause, became to narrow the engineer’s field of view

6 4.Approach to the problem Taking advantage of TRIZ to the desire in the upper layers of the function 1.Taking advantage of the TRIZ
in the purpose and ideal thinking! Converting the function to the desire expression ⇒ Change to the idea of "I want such a thing ! “
2.Eliminate the bondage from the existing system !
By replacing the function of the wide range of the upper layer to the other means, to break down the psychological inertia from the unit or parts ⇒ Taking more advantage of Effects and inventive principles

Can solve the problem concretely. However, the range of ideas is narrow
Can obtain wide innovative idea. However, the idea lacks detail or specifics

Flashlight can not light an
object with weak force
Mechanical unit can not transfer the movement of the hand
to the electrical
unit efficiently
Because Flywheel can not rotate the magnet for a long
time and stable
Because Handle can not rotate the gear efficiently
Because Gear can not rotate the cum fast with low loss
Because Cam rotates the flywheel in only one direction
6-2.①Cause analysis Cause analysis from the upper layer of function tree
Because Spring can not return the handle with weak force

13 6-2.①Definition of contradiction Define the effect to be worse by improving the root cause
Cam rotates the flywheel in only
one direction
improvement:convert all motion
Cam
worse:Structure is complicated
Contradiction Root cause E
improvement:Energy loss worse:complexity of the equipment
Inventive principle:7.Nesting
The solution becomes lose to the cam, Narrow range!

20 6.Summary 1.“I want such a thing !” can take advantage of
TRIZ more with ideal thinking. 2.”Type of Fulfilling the desire” can create
innovative ideas, by breaking down psychological inertia due to the bondage from the unit or parts.
《 Next challenge 》 For Engineers’ inspiration, further investigate the effective approach from case study.
